REUTERS/Benoit Tessier/File Photo Acquire Licensing RightsOct 23 (Reuters) - Bitcoin, the world's largest cryptocurrency, hit a three-month high on Monday, rising 4.73% to $31,420 amid investor enthusiasm about the possibility of a spot bitcoin exchange-traded fund. The rise in bitcoin sent shares of cryptocurrency and blockchain-related companies such as Coinbase Global (COIN.O) and Marathon Digital Holdings (MARA.O) up 6.5% and 11.9% respectively. Bitcoin is up more than 18% from the year's low of $26,533 on Oct. 11. Bitcoin briefly soared on Oct. 16 following an erroneous news report about asset manager BlackRock's high-profile application for a spot bitcoin ETF, which would track the underlying price of the token.
